Answer:
The U.S. government made reservations the centerpiece of Indian policy around 1850, and thereafter reserves became a major bone of contention between natives and non-natives in the Pacific Northwest. However, they did not define the lives of all Indians. Many natives lived off of reservations, for example. One estimate for 1900 is that more than half of all Puget Sound Indians lived away from reservations. Many of these natives were part of families that included non-Indians and children of mixed parentage, and most worked as laborers in the non-Indian economy. They were joined by Indians who migrated seasonally away from reservations, and also from as far away as British Columbia. As Alexandra Harmon's article "Lines in Sand" makes clear, the boundaries between "Indian" and "non-Indian," and between different native groups, were fluid and difficult to fix. Reservations could not bound all Northwest Indians any more than others kinds of borders and lines could.

This became a stepping stone to find a maritime route to Asia.</span>
Answer:
C) Some individual insects are more likely than others to survive and reproduce due to their inherited traits.
Explanation:
Insects are known for their ability to develop resistance to insecticides. Currently there are insects resistant to every synthetic chemical insecticide used. There are many factors to developing resistance, for example:
- many insects species produce large broods. This increases the probability of mutations and ensures the rapid expansion of resistant populations.
- Insects with shorter life times develop resistance more quickly than others because its genetics make them reproduce much faster.
- insects with limited diets are more likely to evolve resistance, because they are exposed to higher pesticide concentrations and has less opportunity to breed with unexposed populations.
But this kind of phenomenon has not only observed in insects in England, rats in certain areas have evolved resistance that allows them to consume up to five times as much rat poison as normal rats without dying.
